Complex interactions among microbes and agricultural systems must be better understood to facilitate the optimal use of beneficial microorganisms and maximal control of pathogens. Opportunities in microbiology research are the gateway to sustaining and improving agriculture and food production, quality, and safety. This book deals with Agricultural Microbiology, metabolism in bacteria, chemoautotrophy, photo-autotrophy, photo-respiration, beneficial microorganisms in agriculture, plant metabolic pathways, carbohydrate metabolism, carbon reduction in C3 plants, sucrose metabolism, starch metabolism, elements of immunology, industrial microbiology and fermentation technology, principle and working of basic equipment and experimentation.
